"kyua report-html" command in CI generates more than two pages of output
to stdout, which is nothing but which HTML pages Kyua generated, e.g.:
Generating kyua_html/context.html
Generating kyua_html/lib_dns_tests_acl_test_main.html
...
Generating kyua_html/lib_ns_tests_query_test_main.html
Generating kyua_html/report.css
Generating kyua_html/index.html
This is seldomly useful and requires the user to scroll three pages
upwards to get to unit test results.
